OILING n EvIOE.

'Application led July 21,

To all whom t 'may concern.'

cal shafts and suchbearings as are equipped with oil catchers below thebearing.

The invention designs to provide a simple and efficient means ofconveying the oil from the oil collecting basin below the bearing to thetop of the bearing where it is directed by gravity thru the bearing. Thepresent arrangement of oiling for guide bearings on vertical shaftsconsists generally in an oil supply bearing, tank, reservoir or pressuremain usually controllable by a valve. After the oil passes thru theguide -bear n 'it is led to a collecting sump and pumped `y mechanicalmeans back to the supply tank, reservoir, or pressure main. Theinvention designs to eliminate. the expensive tanks, pipin and pumps..

he invention will be more readily understood by reference to thedrawings, wherein;

Fig. 1 is a cross-sectional elevation \thru a guide bearing showing asimple form of the ev1ce.

Fig. 2 shows a plan view of the device.

Fig. 3 is a vertical section thru a guide bearing showing a preferredform of the devlce.

Fig. 4 is an elevation o f one'of the guide pulleys 2O rovided withflexible member speed retar ing means.

Fig. 5 is a fragmentar. central vertical section thru the improvelubricator illustrating another form of flexible member speed retardingmeans.

In Fig. 1 it will be noted that a shaft 11 is sup orted by a babbittedguide bearing. An oiishedder 13 deflects the oil from the shaft into anoil reservoir 14. An endless flexible member 15 loops around the shaftabove the babbitted guide bearing and loops into the oil in the Oilreceiver 14 disposed below the ide bearing. The chain is su orted anheld in positionA by pulleys 16,1%. e chain need not necessarily revolveat the linear speed of the shaft but by reasony of 1921. Serial y11'0.486,413.

the. weight of the vertical 'portion of the chain that part of the chainlooped around the shaft is caused to bear with suilioient force to causethe chain to. rotate. A vertical loop of the chain in dipping below theoil in the oil reservoir 14 collects the oil and the oil adheres to thechain and is` drawn up over the pulley 16 around the shaft, and aportion of the oil adheres to the shaft passing down and lubricating thebabbitted bearing- 12. Catch .basins 18, 19 are disposed -underneath thepulleys to catch the oil taken from the chain by the pulleys. Thesecatch basins are designed to guide the oil into the guide bearing 12. v

Fig. 3 illustrates my preferred form of oiling device wherein the bottomof the vertical loop of the flexible member is'passed around a pulley 20disposed in the oil space of the oil chamber 14. Thel pulley 20 providesfor fixing definitely the position of the flexible member with relationto the oil reservoir 14.

The pulley 20 has a sharp V groove as shown in Fig. 4. The flexiblemember 15 binds between the sharp angles of the groove pulley and causesthe grooved pulle ,to rotate substantially at the linear Spee of theflexible member. Wing vanes 21, 21 arev positioned on the grooved pulleyto retard the motion of the pulley in the'oil by means of the frictionof the wing vanes in the oil. One of the pulleys 16 supporting theflexible member' is mounted upon a movable carriage 22l and a spring 23whose tension may be adjusted by means of an adjustable nut 24, providesfor adjusting the tension in the flexible member 15. By adjustment oftheladjusting' screw 24 the tension in the flexible member 15 passingaround the vertical shaft 11 may be adjusted so that the rotating speedof the flexible member may be made any desired amount at will, that is.providing for the drawing up of anyfdesired amount of oil from thereservoir 1-4. to the top of the guide bearing 12 so as to best suit thespeed or conditions under which the shaft is being ,operated andtheamount of oil being required for the lubrication of the bearing. Mypreferred arrangement is to have the flexible member in duplicate sothat in case of thebreakage of one member the other will maintainlubrication.

It will be obvious that instead of varying the. pressure between theflexiblemember. 1 5 and the shaft 11 with the aid of adjustclaims mayoccur to persons .ing member 25 surrounds ing devices such asillustrated in Fig. 3, such adjustment -ma be effected within theflexible member itse f. In the case where a coiled spring is utilized asa flexible member, for instance, the degree of tension in the spring maybe readily varied by enlarging or diminishing the number of coils, thatis automatically varyin the engaging pressure of the flexible memeragainst the shaft 11 and simultaneously varying the rate of travel ofthe member.

Where it is desired to secure an abundant supply of lubrication for thebearing, a device such as illustrated in Fig. 5 may be utilized. In thisdevice a tubular conductone of thejvertical stretches of the flexiblemember' 15 which may be provided with lateral projections or other meansfor positively conducting lubricant from the well 14 thru the conductor25 and to the vertical shaft bearirrg. Besides serving to augment theflow of lubricant to the bearing, the conductor 25 and the flexiblemember l5 co-operating therewith, serve to retard the speed of themember l5.

It should be understoodthat it siredV to limit the scope of thisinvention to the exact details of construction Aand of operation hereinshown and described, as obvious modifications within the scope of theskilled in the art.
